🌱 How to Care for Ivy to Prevent Bacterial Leaf Spot?

💧 How to Water

Water when the top 1–2 cm of soil feels dry, approximately every 7 days. Never let the plant sit in standing water. Reduce watering in winter when growth slows. Overwatering is the most common cause of death in ivy — yellowing leaves and mushy stems are warning signs.

☀️ Lighting

Provide bright, indirect light for best growth and vibrant foliage. Variegated cultivars need more light to retain their patterning. All-green types tolerate lower light but will grow more slowly. Avoid direct afternoon sun, which scorches the leaves, and deep shade, which causes sparse, leggy growth.

🪴 Ideal Soil

Use a well-draining potting mix with a slightly acidic to neutral pH of 6.0–7.5. A blend of loamy potting soil with perlite works well. Avoid overly dense or moisture-retaining soils that can lead to root rot.
